  • Short notes for revision

  • Formula sheets

  • Reaction charts

  • Flashcards

  • Highlighted concepts

Quick revision materials help save time and improve retention.

Solve IAT Previous Year Questions

Previous year questions help students understand:

  • Question difficulty level

  • Important concepts

  • Repeated patterns

  • Time management strategies

Try solving papers in a timed environment to simulate the real exam experience.

Attempt Mock Tests Regularly

Mock tests are one of the most effective last-minute preparation tools. They help students achieve the following objectives:

  • Improve speed and accuracy

  • Identify weak areas

  • Reduce exam anxiety

  • Build confidence

Focus on Accuracy Over Guesswork

Since IAT includes negative marking of a -1 mark, random guessing can reduce overall scores. Attempt questions carefully and avoid unnecessary risks.

A good strategy to approach the questions, include the following steps:

  • Solve easy questions first

  • Mark doubtful questions for review

  • Return to difficult questions later

This approach helps maximise attempts while maintaining accuracy.

Improve Time Management

Students often struggle with balancing all four subjects during the exam. Practice sectional time management while solving mock tests.

A balanced strategy may include:

  • Starting with your strongest subject

  • Avoiding spending too much time on one question

  • Keeping the final few minutes for review

Consistent practice improves speed naturally.

Do Not Start New Topics Now

Learning completely new chapters in the final days can create confusion and increase stress. Instead:

  • Strengthen already prepared topics

  • Revise concepts repeatedly

  • Practice more questions from familiar chapters

Strong command over known topics is more beneficial than partial understanding of new ones.

Maintain a Healthy Routine

Your performance also depends on physical and mental health. During the last few days:

  • Sleep properly

  • Stay hydrated

  • Avoid excessive screen time

  • Take short breaks while studying

  • Eat balanced meals

A fresh and focused mind performs much better in competitive exams.

Prepare Exam-Day Essentials

Keep all important items ready before the exam day. These items include the following:

  • IAT 2026 Admit card

  • Valid ID proof

  • Required stationery

  • Water bottle (if allowed)

Also, check the exam centre location in advance to avoid last-minute panic.

Stay Calm and Confident

The final days of the IAT 2026 preparation should be focused on revision and confidence-building, not stress. Avoid comparing your preparation with others. Trust your preparation and stay consistent with practice.

Even small improvements in accuracy, revision, and time management can make a major difference in your final IAT score.

Conclusion

The IAT 2026 last-minute preparation should focus on smart revision, mock tests, previous year questions, and maintaining confidence. Avoid overloading yourself with new topics and concentrate on strengthening concepts you already know well.

With proper strategy, consistency, and a calm mindset, students can perform effectively in the IISER Aptitude Test and improve their chances of securing admission to top IISERs.
